Instagram is transforming the food scene, and more than ever you can track the progress of wellness conversations on a simple social media app. Whenever a new diet trend arises, there's a hashtag. Whenever a new café pops up with an innovative use for avocados, Instagram is already on it. The new Instagram story function has allowed bloggers and influencers to detail their daily practices and rituals to devout followers, teaching people how to make their own collagen waffles and protein oats.
